We are pleased to announce the release of phpBB 3.1.10 "Bertie's Indian summer". This version is a maintenance & security release of the 3.1.x branch which fixes one trivial security issue and various smaller bugs. The security issue only affects users using no longer supported versions of browsers as well as improperly setup webservers (thanks to Lukas Reschke of Nextcloud for reporting this).
The bugfixes address the Q&A captcha logging errors when it was solved, fatal errors when upgrading from 3.0.x in certain cases, and database transactions not being rolled back with incorrect notification settings. Other changes include an improved migrator and hardened form checking in the Admin Control Panel.
It also adds support for UI tests in extensions and now checks the version constant against the config version to notify users of incomplete updates.
